Ship Design and Appearance
The ship is a small, metal raft shaped like a bullet. It is yellow with green underneath, and has a red "H-1" painted on the front. The craft can also mount Henzo's Rainbow Mist tracking device on the back of it. The ship is pedal operated.
Henzo first used the H-1 to travel out to the sea to investigate the Tarielishin. When he found nothing on the ship, he said H-1 couldn't go to the Rainbow Mist, because she wasn't designed to be capable of going long distances.
